BATTERY OPERATION
Fuel Gauge
Use the Fuel Gauge on the battery pack to
determine the battery pack's remaining run time.
Press the Fuel Gauge button to display the lights.
The Fuel Gauge will light up for 2-3 seconds. When
less than 10% of charge is left, 1 light on the fuel
gauge will flash slowly.

NOTE: If the Fuel Gauge doesn't appear to be
working, place the battery pack on the charger and
charge as needed.

MILWAUKEE
Lithium-Ion battery packs deliver
®
fade-free power for their entire run time. The tool
will not experience a slow, gradual loss of power as
you work. To signal the end of discharge, 1 light on
the fuel gauge will flash quickly for 2-3 seconds and
the tool will not run. Charge the battery pack.
NOTE: Immediately after using the battery pack,
the Fuel Gauge may display a lower charge than it
will if checked a few minutes later. The battery cells
"recover" some of their charge after resting.
Battery Pack Protection
To protect itself from damage and extend its life, the
battery pack's intelligent circuit monitors current
draw and temperature. In extremely high torque,
binding, stalling, and short circuit situations, the
battery pack will turn OFF the tool if the current
draw becomes too high. All the fuel gauge lights will
flash. Release the trigger and restart.
Under
extreme
circumstances,
temperature of the battery could become too high. If
this happens, the fuel gauge lights will flash in an
alternating pattern and the tool will not run. Allow
the battery to cool down.

designed to operate in temperatures below freezing.
When the battery pack is too cold, it may need to
warm up before normal use. Put the battery on a tool
and use the tool in a light application. It may "buzz"
for a short time until it warms up. When the buzzing
stops, use the tool normally.

Maintenance and Storage
Do not expose your battery pack or cordless tools
to water or rain, or allow them to get wet. This could
damage the tool and battery pack. Do not use oil or
solvents to clean or lubricate your battery pack. The
plastic casing will become brittle and crack, causing
a risk of injury.
Store battery packs at room temperature away from
moisture. Do not store in damp locations where
corrosion of terminals may occur. As with other
battery pack types, permanent capacity loss can
result if the pack is stored for long periods of time at
high temperatures (over 49°C). MILWAUKEE
Lithium-Ion battery packs maintain their charge
during storage longer than other battery pack types.
After about a year of storage, charge the pack as
normal.
Personal transport of Li-Ion battery packs is allowed
when done in accordance with these warnings and
beling, marking, and documentation requirements for
shipping Li-Ion batteries is dependent upon whether
the particular batteries are rated greater than or less
than 100 Wh (Watt Hours can be found on the battery
pack nameplate). Generally, Li-Ion batteries rated
100 Wh or less are "excepted" from certain Class 9
DG requirements. Always check compliance of Li-Ion
battery consignments against the current regulations
governing the chosen mode of transport. When in
doubt, contact the carrier or other trained Dangerous
(battery only) or UN 3481 (batteries contained in or
packed with equipment).
To reduce the risk of injury or ex-
WARNING
plosion, never burn or incinerate a
battery pack even if it is damaged, dead or com-
pletely discharged. When burned, toxic fumes
and materials are created.
Disposing of MILWAUKEE
MILWAUKEE
Lithium-Ion battery packs are more
®
environmentally friendly than some other types of
power tool battery packs (e.g., nickel-cadmium).
Always dispose of your battery pack according to
federal, state and local regulations. Contact a
recycling agency in your area for recycling
locations.
Even discharged battery packs contain some
energy. Before disposing, use electrical tape to
cover the terminals to prevent the battery pack from
shorting, which could cause a fire or explosion.
